CADMIUM-MERCURY TELLURIDE SURFACE PASSIVATING TECHNIQUE

摘要

infrared photodetector manufacture. SUBSTANCE: semiconductor surfaces are subjected to chemical treatment and passivating to obtain thick (up to 3000 A) passivating coatings dispensing with additional protection on CdxHg1-x surface within short time. Sulfidizing solution for passivating film is made of following ingredients, mass percent: sulfur - 0,3- 6; sodium or potassium hydroxide (45% aqueous solution) - 94-99.7. EFFECT: improved efficiency of process and quality of passivating film.
